Wavelength and Color: Understanding Visible Light and the Electromagnetic Spectrum

The video explores the visible light portion of the electromagnetic spectrum, explaining how it is sandwiched between ultraviolet and infrared light. It discusses the continuous spectrum of colors, the scattering of sunlight by Earth's atmosphere, and how this affects the sun's appearance at different times of the day. The concept of refraction is introduced, showing how white light can be split into its constituent colors using a prism. Different light sources and their emission spectra are also covered.
